EDIVARD HUBER, OF MARION, OHIO.

BOLT.

SPECIFICATION forming part of Letters Patent No. 447,516, dated March 3, 1891.

Application filed October 29, 1890. Serial No. 369,693. (No model.)

To aZl whom it may concern.-

Be it known that I, EDWARD HUBER, a resident of Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in T-Bolts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in bolts, and more particularly to such as are adapted for use in securing the cross-bars or slats to the longitudinal straps of an endless conveyer, the object being to produce a bolt by means of which the slats or cross-bars of an endless conveyer may be secured to the longitudinal straps in such manner that all liability to torsional action of said conveyer will be effectually prevented.

A further object is to produce a bolt by means of which two or more articles may be secured together, and lateral movement as well as turning or twisting of said articles will be effectually prevented.

lVith these objects in view the invention consists in a T-bolt having, preferably, a screwthreaded shank and a spur or projection integral with and at or near one end of the head of said bolt and adapted to pass through the articles being secured together.

The invention further consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of a portion of a conveyer, showing the application of my improved bolt thereto. Fig. 2 is a sectional view through one of the slats, belt, and bolt. Fig. 3 is a detached view of the bolt.

For the sake of illustration I have shown and will describe my invention in connection with an endless conveyer, although it is evident that it is equally applicable for securing together parts of other constructions.

A represents one of the longitudinal straps of an endless conveyer, and B one of the crossbars or slats arranged at right angles thereto and adapted to connect said strap with one or more parallel straps. At the junction of the straps A and slats B said parts are secured together by means of my improved bolt 0. This bolt comprises a head at, having an approximately fiat under surface and adapted to lie flat on the strap-A, a shank 1), adapted to pass through the strap and slat or crossbar, and spurs or projections c d. The free end of the shank is provided with screwthreads for the reception of a suitable nut e. The spur or projection c, which is located in proximity to one end of the head A, is made integral with said head, and projecting downwardly parallel with the shank B is adapted to pass through the web or strap A and into the slat or cross-bar B, said spur or projection being preferably made fiat and of V shape. The spur or projection cl projects downwardly from the head a in proximity to the opposite end th reof from the projection c, and is adapted simply to enter the strap A, as shown in Fig. 2. If desired, the shank b may be made to project from the head a at a point slightly removed from the center of the latter.

It will be clearly seen that by the employment of a bolt constructed and'attached in the manner above set forth the parts which it is designed to secure together will be effectually prevented from the least lateral or turning movement, and that the conveyor as a whole will be prevented from torsion.

Having f ully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A T-bolt the head of which is approximately fiat on its under side and provided near one end with an integral spur or projection, the latter extending parallel with the shank of the bolt, substantially as set forth.

2. A T-bolt the head of which is approximately flat on its lower surface and provided near one end with an integral depending fiat spur, the latter extending parallel with'the shank of the bolt, substantially as set forth.

3. A T-bolt the head of which is approximately flat on its lower surface and provided near one end with an integral depending V,- shaped spur, the latter extending parallel with the shank of the bolt, substantially as set forth.

4. A T-bolt having an integral depending spur at one end of the head thereof adapted to extend parallel with the shank of said bolt, and an integral depending spur at the other end of said head, substantially as set forth.
